What is the value of one Megabit (Mb) in bits?

One Megabit (Mb) is equal to 1,000,000 bits. The metric system defines prefixes based on powers of ten, where "Mega" indicates a factor of one million (10^6). Therefore, when converting Megabits to bits, you multiply by one million. This value is particularly important in networking and data transfer contexts, where understanding data rates and file sizes is crucial.

The other choices involve larger values that do not correspond to the correct conversion from Megabits to bits. For instance, one Gigabit (Gb) would be 1,000,000,000 bits, and one Terabit (Tb) would be 1,000,000,000,000 bits, both of which are not applicable when determining the value of one Megabit.
